Be it known thatI,SoLoMoNMAY, a citizen of the United States, residing' at. Chi

cago, in the county of Cook and State of ful Improvements. in Casings and -Methods of Making Same, of which the following is a specification. l

The present invention relates to casings and methods of making same.

In manufacturing casings" for sausages and similar articles, itis common practice to use the bladders, intestines,ior other saclike organs of animals. Inasmuch'as cer-r 15 tain sizes and shapes are demanded byithe trade, the field of choice i i is limited. p

An object of the present invention is to provide a method of manufacturing casings whereby two ofisuch organs may be combinedto provide a casing of the requisite size and s ape.

A further object is to provide a method whereby organs such as referr ed to above may be conveniently handled.

. A further object is to provide a casing built up of a pluralityuof animal organs which will have improved 'attractivenessand which will conform to the requirements of the trade.

Further objectswill appear as the description proceeds;

Referring to drawings.

Figure 2 represents a bladder similar. to that "shown in Figural, but turned inside out whereby the slimy'side'is outermost;

The numeral 10 illustrates a sac-like mem-l branous member, which may be thei'bladder among such organs ferences in natural contour.

point the bladder will be handled in moist or part of the intestines of an animal such as a hog. I Said member 10, which for con- 7 venience herein will be termed a bladder, p is imperforate except for the neck'll which 5 Illinois, have invented certain new and userovides access. to the interior of said blader. A second bladder is illustrated in Figure 2, said second bladder being turned in-, side out, whereby the slimy side is outermost. The body of the bladder illustrated in Figure 2 is indicated by the numeral 12 and the neck thereof is indicated by the numeral 13. Any preferred means may be used for turning a bladder inside out, but it will be found convenient to use a tube, carrying compressed air, for this purpose.

Figure 3 illustrates a bladder which has been turned inside out mounted within a bladder which is in its normal condition.

Any preferred method may be used for inwithin the neck 11 of the bladder illustrated in Figure 1. If difliculty is encountered in this operation, air under pressure may be applied to the tube 1 1 and said air will cause the bladder 11 to enter the bladder 10. In any event, whether or not air under pressure is used'inthe insertingoperation,

it is preferred to use airxunder pressure to inflate the innermost bladder whereby the 'two bladders arefo-rred into intimate contact with one another. By this method the' result is produced that the one bladder fitsv tightly within the other, regardless of dif Up to this condition. The natural flexibility of said bladders will accommodate differences in size and contour. I

After the two bladders have been mounted one within the other the neck 13 will be tied to prevent escape of air and said bladders will be'allowed to dry, after which that end of the composite structure whichis opposite to the neck 11 will be cut away along the'line indicated by the numera'ls1515. The remaining parts ofthe two bladders will then be sewed: or otherwise attached together along a seam indicated by the numeral 16. The fact that the two bladders are in such intimate contact, and therefore fit together very well, renders it a simple matter to sew the two bladders together. The resulting structure is a cup-shaped structure having an apex located at the.

neck 11.

The composite structure having the cup shap'e formation is then soaked. inwater whereby to loosen the two bladders, the air tube is then inserted on the .insideot the cup, and the inside bladder 12 is then blown out through the neck 11, the structure being thereby turned so that the slimy side is out ermostr The resulting structure is illuscut edges to form a fabricated casing.

Theseand othermeth'ods may be employed vention.

The small ends of the bladders may be sewed'together, ifpreferred, to make small casings,'or maybe used in any of the well known waysin which the material of bladders is utilized.

without departing from the spirit of the inhas the advantage that only one tyingoperation is required oneach fabricated structure,the inner bladder only being tied at its neck portion. 9

handling of the composite structure is simplified for the casing maker for the reason that he does not have to untie any strings and 1s 'slmplified for the sausage maker for the reason that one end of the composite 1 structure is already tied. leaving only the It may be noted" that the filling opening. term sac-like as used herein is intended. to refer'to a structure having either one aperture or a plurality of apertures.

The resulting fabricated structure is niaterially longer than a casing which consists of' only one of the bladders from which said fabricated casing is made. There is considerable'latitude 1n the location of the line 1515along which the cutting is done. for the reason that the flexibility and expansibility of the bladders permits stretching under the influence of the compressed air.

'Theresulting casing is very sturdy and'permits the use of small. bladders in the manufacture ofcasingsof a size to conform to the requirements of the trade:

The invention is also applicable to intestines, for the reason that it permits the fabrication of casings from the most suitable parts of said intestines.

One embodiment of the present invention has been described in detail. Many modifications will te'ur tothose skilled in the art. Itisintended inthispatent to cover all such modifications thatfall within the scope of the-{invention asydefined by the appended claims.

I claim: 1. The method of making casings which consists of inserting a sac-like member having an outer slimy side within a sac-like member having a slimy inner side, forcing said slimy sides into'intimate contact with one another, attaching said members together along a seam, parts of said members being removed along one side-of said seam, and turning the resulting-structure so that the slimy side is outermost.

2; The method ofmaking'casingswhich consists of inserting asac-like member havingwa slimy outer side within asac-like -member having a slimy inner side, forcing.

said slimy sides into intimate contact with stitching,- and turningwthe resulting com-- posite structure so that the slimy side is outermost.
